System recovery built into Windows 7

Question

If I'm not using Lenovo's ThinkVantage Rescue & Recover on Think products, or One Key Recovery on Idea products, what are the system recovery options built into Windows 7?

Answer

The System Recovery Options menu contains several tools, such as Startup Repair, that can help you recover Windows from a serious error. This set of tools is on your computer's hard disk and on the Windows installation disc.

Restores your computer's system files to an earlier point in time without affecting your files, such as e‑mail, documents, or photos.

If you use System Restore from the System Recovery Options menu, you cannot undo the restore operation. However, you can run System Restore again and choose a different restore point, if one exists. For more information, see System Restore: frequently asked questions.

System Image Recovery

You need to have created a system image beforehand to use this option. A system image is a personalized backup of the partition that contains Windows, and includes programs and user data, like documents, pictures, and music. For more information, see What is a system image?
